Here, in this post you will find the detailed code for establishing socket between devices or between two application in the same mobile.

You have to create two application to test below code.

In both application's manifest file, add below permission

<uses-permission android:name="android.permission.INTERNET" />

1st App code: Client Socket

It worked well for me. Just one line code in cmd.

First, confirm that you have installed the gcc (for c) or g++ (for c++) compiler.

In cmd for gcc type:

gcc --version

in cmd for g++ type:

g++ --version

If it is installed then proceed.

Now, compile your .c or .cpp using cmd

for .c syntax:

gcc -o exe_filename yourfilename.c

Example:

gcc -o myfile myfile.c

Here exe_filename (myfile in example) is the name of your .exe file which you want to produce after compilation (Note: i have not put any extension here). And yourfilename.c (myfile.c in example) is the your source file which has the .c extension.

Now go to folder containing your .c file, here you will find a file with .exe extension. Just open it. Hurray..

For .cpp syntax:

g++ -o exe_filename yourfilename.cpp

After it the process is same as for .c .

It is not that truncate does not log anything in SQL Server. truncate does not log any information but it log the deallocation of data page for the table on which you fired TRUNCATE.

and truncated record can be rollback if we define transaction at beginning and we can recover the truncated record after rollback it. But can not recover truncated records from the transaction log backup after committed truncated transaction.

Here, the program asks the user to enter a number. After that, the program prints the digits of the number and the sum of the digits.

import java.util.Scanner;

public class PrintNumber {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        int num = 0;
        int sum = 0;

        System.out.println(
            "Please enter a number to show its digits");
        num = scan.nextInt();

        System.out.println(
            "Here are the digits and the sum of the digits");
        while (num > 0) {
            System.out.println("==>" + num % 10);
            sum += num % 10;
            num = num / 10;   
        }
        System.out.println("Sum is " + sum);            
    }
}

I faced same error after updating my ubuntu to next version

I just deleted my sshkey on github account and then re added an sshkey to that account.

My first answer ever in the hope that it'll be usefull to someone : I now this is an old question but I encountered exactly the same error as the above question as I'm writing a TcpServer class and I was trying to use pthreads. I found this question and I understand now why it was happening. I ended up doing this:

#include <thread>

method to run threaded -> void* TcpServer::sockethandler(void* lp) {/*code here*/}

and I call it with a lambda -> std::thread( [=] { sockethandler((void*)csock); } ).detach();

that seems a clean approach to me.

From Linux Change Default User Home Directory While Adding A New User:

Simply open this file using a text editor, type:

vi /etc/default/useradd

The default home directory defined by HOME variable, find line that read as follows:

HOME=/home

Replace with:

HOME=/iscsi/user

Save and close the file. Now you can add user using regular useradd command:

# useradd vivek
# passwd vivek

Verify user information:

# finger vivek

You can also use a proxy tool like Charles to capture the outgoing request headers, data, etc. by passing the proxy details through CURLOPT_PROXY to your curl_setopt_array method.

For example:

$proxy = '127.0.0.1:8888';
$opt = array (
    CURLOPT_URL => "http://www.example.com",
    CURLOPT_PROXY => $proxy,
    CURLOPT_POST => true,
    CURLOPT_VERBOSE => true,
    );

$ch = curl_init();
curl_setopt_array($ch, $opt);
curl_exec($ch);
curl_close($ch);

I know this is an old one but it comes up top of Google and all the links provided now seem out of date.

This is the latest list of types Facebook accepts: https://developers.facebook.com/docs/reference/opengraph

If you don't use one of these then the type will default to 'website' which is best used for home pages/summarising a web site.

In answer to the OP you would now want to use a place which will allow you to add lat/long location details.

Try this when you dont want user to redirect on click

<a href="javascript: void(0)">I am a useless link</a>

how about making the heading a list-element with different styles like so

<ul>
 <li class="heading">heading</li>
 <li>list item</li>
 <li>list item</li>
 <li>list item</li>
 <li>list item</li>
</ul>

and the CSS

ul .heading {font-weight: normal; list-style: none;}

additionally, use a reset CSS to set margins and paddings right on the ul and li. here's a good reset CSS. once you've reset the margins and paddings, you can apply some margin on the list-elements other than the one's with the heading class, to indent them.

It means or-equals to. It checks to see if the value on the left is defined, then use that. If it's not, use the value on the right. You can use it in Rails to cache instance variables in models.

A quick Rails-based example, where we create a function to fetch the currently logged in user:

class User > ActiveRecord::Base

  def current_user
    @current_user ||= User.find_by_id(session[:user_id])
  end

end

It checks to see if the @current_user instance variable is set. If it is, it will return it, thereby saving a database call. If it's not set however, we make the call and then set the @current_user variable to that. It's a really simple caching technique but is great for when you're fetching the same instance variable across the application multiple times.

Commons Lang has it. Or you could throw an UnsupportedOperationException.

My code was broken because I was using a deprecated technique. It used to be this:

video.src = window.URL.createObjectURL(localMediaStream);
video.play();

Then I replaced that with this:

video.srcObject = localMediaStream;
video.play();

That worked beautifully.

EDIT: Recently localMediaStream has been deprecated and replaced with MediaStream. The latest code looks like this:

video.srcObject = new MediaStream();

References:

To figure out if an Integer is greater than 0, you can:

• check if compareTo(O) returns a positive number:

  if (count.compareTo(0) > 0)
       ...
  

  But that looks pretty silly, doesn't it? Better just...

• use autoboxing¹:

  if (count > 0)
      ....
  

  This is equivalent to:

  if (count.intValue() > 0)
      ...
  

  It is important to note that "==" is evaluated like this, with the Integer operand unboxed rather than the int operand boxed. Otherwise, count == 0 would return false when count was initialized as new Integer(0) (because "==" tests for reference equality).

¹Technically, the first example uses autoboxing (before Java 1.5 you couldn't pass an int to compareTo) and the second example uses unboxing. The combined feature is often simply called "autoboxing" for short, which is often then extended into calling both types of conversions "autoboxing". I apologize for my lax usage of terminology.

Here's what I currently use for deleting or even, updating:

DELETE           w
FROM             WorkRecord2   w,
                 Employee      e
WHERE            w.EmployeeRun = e.EmployeeNo
             AND w.Company = '1' 
             AND w.Date = '2013-05-06'

The correct answer to this is that you shouldn't. If you want this type of thing either just use a dict, or you'll need to explicitly add attributes to some container. You can automate that by learning about decorators.

In particular, by the way, method1 in your example is just as good of an attribute.

When it is the case that you want to use any kind of external file, there is certainly a way to put them in a folder within your project, but not as valid as getting them from resources. In a regular Visual Studio project, you should have a Resources.resx file under the Properties section, if not, you can easily add your own Resource.resx file. And add any kind of file in it, you can reach the walkthrough for adding resource files to your project here.

After having resource files in your project, calling them is easy as this:

var myIcon = Resources.MyIconFile;

Of course you should add the using Properties statement like this:

using <namespace>.Properties;

It will be better to Create a New role, then grant execute, select ... etc permissions to this role and finally assign users to this role.

Create role

CREATE ROLE [db_SomeExecutor] 
GO

Grant Permission to this role

GRANT EXECUTE TO db_SomeExecutor
GRANT INSERT  TO db_SomeExecutor

to Add users database>security> > roles > databaseroles>Properties > Add ( bottom right ) you can search AD users and add then

OR

   EXEC sp_addrolemember 'db_SomeExecutor', 'domainName\UserName'

There are two very different types of pages in SharePoint: Application Pages and Site Pages.

If you are going to use your page as an Application Page, you can safely use inline code or code behind in your page, as Application pages live on the file system.

If it's going to be a Site page, you can safely write inline code as long as you have it like that in the initial deployment. However if your site page is going to be customized at some point in the future, the inline code will no longer work because customized site pages live in the database and are executed in asp.net's "no compile" mode.

Bottom line is - you can write aspx pages with inline code. The only problem is with customized Site pages... which will no longer care for your inline code.

When you register for a new website, often you are sent an email to activate your account. That email typically contains a link to click on. Part of that link, contains a token, the server knows about this token and can associate it with your account. The token would usually have an expiry date associated with it, so you may only have an hour to click on the link and activate your account. None of this would be possible with cookies or session variables, since its unknown what device or browser the customer is using to check emails.

The easiest way is to add android:windowSoftInputMode="stateAlwaysHidden" in the activity tag of the Manifest.xml file

Specifically...

How and where is app.run() used? After module definition or after app.config(), after app.controller()?

Where:

In your package.js E.g. /packages/dashboard/public/controllers/dashboard.js

How:

Make it look like this

var app = angular.module('mean.dashboard', ['ui.bootstrap']);

Here's a useful PHP function I wrote for this precisely. As the original question clarifies, it returns the path from which the initial script was executed - not the file we are currently in.

/**
 * Get the file path/dir from which a script/function was initially executed
 * 
 * @param bool $include_filename include/exclude filename in the return string
 * @return string
 */ 
function get_function_origin_path($include_filename = true) {
    $bt = debug_backtrace();
    array_shift($bt);
    if ( array_key_exists(0, $bt) && array_key_exists('file', $bt[0]) ) {
        $file_path = $bt[0]['file'];
        if ( $include_filename === false ) {
            $file_path = str_replace(basename($file_path), '', $file_path);
        }
    } else {
        $file_path = null;
    }
    return $file_path;
}

Table or record locking is available in Access during data writes. You can control the Default record locking through Tools | Options | Advanced tab:

1. No Locks
2. All Records
3. Edited Record

You can set this on a form's Record Locks or in your DAO/ADO code for specific needs.

Transactions shouldn't be a problem if you use them correctly.

Best practice: Separate your tables from All your other code. Give each user their own copy of the code file and then share the data file on a network server. Work on a 'test' copy of the code (and a link to a test data file) and then update user's individual code files separately. If you need to make data file changes (add tables, columns, etc), you will have to have all users get out of the application to make the changes.

See other answers for Oracle comparison.

I strongly recommend BOUML which:

• is extremely fast (fastest UML tool ever created, check out benchmarks),
• has rock solid PHP import and export support (also supports C++, Java, Python)
• is multiplatform (Linux, Windows, other OSes),
• is full featured, impressively intensively developed (look at development history, it's hard to believe that such fast progress is possible).
• supports plugins, has modular architecture (this allows user contributions, looks like BOUML community is forming up)

I'm on debian linux amd64. I installed oracle's Java 11 from oracle's java download page. Installed eclipse from eclipse.org. Running eclipse produced the "cannot load swt" error. I followed ATorras's advice and did apt install libswt-gtk-4-jni (which also installed a ton of other things) and after that eclipse started. Although it started I did get the following errors/warnings:

org.eclipse.m2e.logback.configuration: The org.eclipse.m2e.logback.configuration bundle was activated before the state location was initialized.  Will retry after the state location is initialized.

I think I can ignore most if not all of that. I'm doing an ssh into the linux box using mobaXterm on my windows pc, so it's displaying its window on my pc. My linux box is headless.

Probably AES. Blowfish was the direct predecessor to Twofish. Twofish was Bruce Schneier's entry into the competition that produced AES. It was judged as inferior to an entry named Rijndael, which was what became AES.

Interesting aside: at one point in the competition, all the entrants were asked to give their opinion of how the ciphers ranked. It's probably no surprise that each team picked its own entry as the best -- but every other team picked Rijndael as the second best.

That said, there are some basic differences in the basic goals of Blowfish vs. AES that can (arguably) favor Blowfish in terms of absolute security. In particular, Blowfish attempts to make a brute-force (key-exhaustion) attack difficult by making the initial key setup a fairly slow operation. For a normal user, this is of little consequence (it's still less than a millisecond) but if you're trying out millions of keys per second to break it, the difference is quite substantial.

In the end, I don't see that as a major advantage, however. I'd generally recommend AES. My next choices would probably be Serpent, MARS and Twofish in that order. Blowfish would come somewhere after those (though there are a couple of others that I'd probably recommend ahead of Blowfish).

Below code changes to 'datetime' type and also formats in the given format string. Works well!

df['DOB']=pd.to_datetime(df['DOB'].dt.strftime('%m/%d/%Y'))

Maybe a little late to the party but why don't you use sessions to store your data?

bookingfacilities.php

session_start();
$_SESSION['form_date'] = $date;

successfulbooking.php

session_start();
$date = $_SESSION['form_date']; 

Nobody will see this.

Because there are two print statements. First is inside function and second is outside function. When function not return any thing that time it return None value.

Use return statement at end of function to return value.

e.g.:

Return None value.

>>> def test1():
...    print "In function."
... 
>>> a = test1()
In function.
>>> print a
None
>>> 
>>> print test1()
In function.
None
>>>
>>> test1()
In function.
>>> 

Use return statement

>>> def test():
...   return "ACV"
... 
>>> print test()
ACV
>>> 
>>> a = test()
>>> print a
ACV
>>> 

class1 item = lst[index];
item.foo = bar;

You haven't provided your javascript code, but the usual cause of this type of issue is not waiting till the page is loaded. Remember that most javascript is executed before the DOM is loaded, so code trying to manipulate it won't work.

To run code after the page has finished loading, use the $(document).ready callback:

$(document).ready(function(){
  $('#some-id').trigger('click');
});

Along with jerjer answer(top), sometimes in your parent window and child window are not both external or both internal you will see a problem of opener undefined, and you cannot access parent page properties, see window.opener is undefined on Internet Explorer

You want to git rebase -i to perform an interactive rebase.

If you're currently on your "commit 1", and the commit you want to merge, "commit 2", is the previous commit, you can run git rebase -i HEAD~2, which will spawn an editor listing all the commits the rebase will traverse. You should see two lines starting with "pick". To proceed with squashing, change the first word of the second line from "pick" to "squash". Then save your file, and quit. Git will squash your first commit into your second last commit.

Note that this process rewrites the history of your branch. If you are pushing your code somewhere, you'll have to git push -f and anybody sharing your code will have to jump through some hoops to pull your changes.

Note that if the two commits in question aren't the last two commits on the branch, the process will be slightly different.

Take a look at this JQuery plugin:

http://fixedheadertable.com

It adds vertical (fixed header row) or horizontal (fixed first column) scrolling to an existing HTML table. There is a demo you can check for both cases of scrolling.

pandas >= 1.1: DataFrame.compare

With pandas 1.1, you could essentially replicate Ted Petrou's output with a single function call. Example taken from the docs:

pd.__version__
# '1.1.0'

df1.compare(df2)

  score       isEnrolled       Comment             
   self other       self other    self        other
1  1.11  1.21        NaN   NaN     NaN          NaN
2   NaN   NaN        1.0   0.0     NaN  On vacation

Here, "self" refers to the LHS dataFrame, while "other" is the RHS DataFrame. By default, equal values are replaced with NaNs so you can focus on just the diffs. If you want to show values that are equal as well, use

df1.compare(df2, keep_equal=True, keep_shape=True) 

  score       isEnrolled           Comment             
   self other       self  other       self        other
1  1.11  1.21      False  False  Graduated    Graduated
2  4.12  4.12       True  False        NaN  On vacation

You can also change the axis of comparison using align_axis:

df1.compare(df2, align_axis='index')

         score  isEnrolled      Comment
1 self    1.11         NaN          NaN
  other   1.21         NaN          NaN
2 self     NaN         1.0          NaN
  other    NaN         0.0  On vacation

This compares values row-wise, instead of column-wise.

I try lots of ways and finally try this:

def db_persist(func):
    def persist(*args, **kwargs):
        func(*args, **kwargs)
        try:
            session.commit()
            logger.info("success calling db func: " + func.__name__)
            return True
        except SQLAlchemyError as e:
            logger.error(e.args)
            session.rollback()
            return False

    return persist

and :

@db_persist
def insert_or_update(table_object):
    return session.merge(table_object)

You can use like this:

case 4: case 2:
 {
   //code ...
 }

For use 4 or 2 switch case.

Here's another variation, using an array to pop off whatever values you want.

const a = {_x000D_
  n: [3,2,1],_x000D_
  toString: function () {_x000D_
    return a.n.pop();_x000D_
  }_x000D_
}_x000D_
_x000D_
if(a == 1 && a == 2 && a == 3) {_x000D_
  console.log('Yes');_x000D_
}

Just an example of how I fixed the problem in an array to load a listView, hope it helps.

 mItems = new ArrayList<ListViewItem>();
//    Resources resources = getResources();

//    mItems.add(new ListViewItem(resources.getDrawable(R.drawable.az_lgo), getString(R.string.st_az), getString(R.string.all_nums)));
//    mItems.add(new ListViewItem(resources.getDrawable(R.drawable.ca_lgo), getString(R.string.st_ca), getString(R.string.all_nums)));
//    mItems.add(new ListViewItem(resources.getDrawable(R.drawable.co_lgo), getString(R.string.st_co), getString(R.string.all_nums)));
    mItems.add(new ListViewItem(ResourcesCompat.getDrawable(getResources(), R.drawable.az_lgo, null), getString(R.string.st_az), getString(R.string.all_nums)));
    mItems.add(new ListViewItem(ResourcesCompat.getDrawable(getResources(), R.drawable.ca_lgo, null), getString(R.string.st_ca), getString(R.string.all_nums)));
    mItems.add(new ListViewItem(ResourcesCompat.getDrawable(getResources(), R.drawable.co_lgo, null), getString(R.string.st_co), getString(R.string.all_nums)));

Use this line of code in your css

border: 1px solid #000 !important;

or if you want border only in left and right side of container then use:

border-right: 1px solid #000 !important;
border-left: 1px solid #000 !important;

                 java.nio.file.LinkOption.NOFOLLOW_LINKS);

Moving a directory or file

long bytes = java.nio.file.Files.move( 
                 new java.io.File("<filepath1>").toPath(), 
                 new java.io.File("<filepath2>").toPath(),

You can not "attach" a SASS/SCSS file to an HTML document.

SASS/SCSS is a CSS preprocessor that runs on the server and compiles to CSS code that your browser understands.

There are client-side alternatives to SASS that can be compiled in the browser using javascript such as LESS CSS, though I advise you compile to CSS for production use.

It's as simple as adding 2 lines of code to your HTML file.

<link rel="stylesheet/less" type="text/css" href="styles.less" />
<script src="less.js" type="text/javascript"></script>

The best way to do it is:

String path = "C:" + File.separator + "hello" + File.separator + "hi.txt";
// Use relative path for Unix systems
File f = new File(path);

f.getParentFile().mkdirs(); 
f.createNewFile();

Try this (replace 'user' with the actual login name):

IF NOT EXISTS(
SELECT name 
FROM [master].[sys].[syslogins]
WHERE NAME = 'user')

BEGIN 
    --create login here
END

Assuming SQL Server:

Table structure:

CREATE TABLE [dbo].[item_dept](
    [ItemName] char(20) NULL,
    [DepartmentID] int NULL   
)

Query:

SELECT ItemName,
       STUFF((SELECT ',' + rtrim(convert(char(10),DepartmentID))
        FROM   item_dept b
        WHERE  a.ItemName = b.ItemName
        FOR XML PATH('')),1,1,'') DepartmentID
FROM   item_dept a
GROUP BY ItemName

Results:

ItemName    DepartmentID
item1       21,13,9,36
item2       4,9,44

check available Java versions on your Linux system by using update-alternatives command:

 $ sudo update-alternatives --display java

Now that there are suitable candidates to change to, you can switch the default Java version among available Java JREs by running the following command:

 $ sudo update-alternatives --config java

When prompted, select the Java version you would like to use.1 or 2 or 3 or etc..

Now you can verify the default Java version changed as follows.

 $ java -version

In order to move a View anywhere on the screen, I would recommend placing it in a full screen layout. By doing so, you won't have to worry about clippings or relative coordinates.

You can try this sample code:

main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" android:id="@+id/rootLayout">

    <Button
        android:id="@+id/btn1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="MOVE" android:layout_centerHorizontal="true"/>

    <ImageView
        android:id="@+id/img1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="10dip"/>
    <ImageView
        android:id="@+id/img2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_centerVertical="true" android:layout_alignParentRight="true"/>
    <ImageView
        android:id="@+id/img3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_alignParentBottom="true" android:layout_marginBottom="100dip"/>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" android:clipChildren="false" android:clipToPadding="false">

        <ImageView
            android:id="@+id/img4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_marginTop="150dip"/>
    </LinearLayout>

</RelativeLayout>

Your activity

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ((Button) findViewById( R.id.btn1 )).setOnClickListener( new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            ImageView img = (ImageView) findViewById( R.id.img1 );              
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img2 );
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img3 );                
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img4 );
            moveViewToScreenCenter( img );
        }
    });
}

private void moveViewToScreenCenter( View view )
{
    RelativeLayout root = (RelativeLayout) findViewById( R.id.rootLayout );
    DisplayMetrics dm = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics( dm );
    int statusBarOffset = dm.heightPixels - root.getMeasuredHeight();

    int originalPos[] = new int[2];
    view.getLocationOnScreen( originalPos );

    int xDest = dm.widthPixels/2;
    xDest -= (view.getMeasuredWidth()/2);
    int yDest = dm.heightPixels/2 - (view.getMeasuredHeight()/2) - statusBarOffset;

    TranslateAnimation anim = new TranslateAnimation( 0, xDest - originalPos[0] , 0, yDest - originalPos[1] );
    anim.setDuration(1000);
    anim.setFillAfter( true );
    view.startAnimation(anim);
}

The method moveViewToScreenCenter gets the View's absolute coordinates and calculates how much distance has to move from its current position to reach the center of the screen. The statusBarOffset variable measures the status bar height.

I hope you can keep going with this example. Remember that after the animation your view's position is still the initial one. If you tap the MOVE button again and again the same movement will repeat. If you want to change your view's position do it after the animation is finished.

Basically, ajax request as well as synchronous request sends your document cookies automatically. So, you need to set your cookie to document, not to request. However, your request is cross-domain, and things became more complicated. Basing on this answer, additionally to set document cookie, you should allow its sending to cross-domain environment:

type: "GET",    
url: "http://example.com",
cache: false,
// NO setCookies option available, set cookie to document
//setCookies: "lkfh89asdhjahska7al446dfg5kgfbfgdhfdbfgcvbcbc dfskljvdfhpl",
crossDomain: true,
dataType: 'json',
xhrFields: {
    withCredentials: true
},
success: function (data) {
    alert(data);
});

You can use the instanceof operator (but see caveat below!).

var myError = new Error('foo');
myError instanceof Error // true
var myString = "Whatever";
myString instanceof Error // false

The above won't work if the error was thrown in a different window/frame/iframe than where the check is happening. In that case, the instanceof Error check will return false, even for an Error object. In that case, the easiest approach is duck-typing.

if (myError && myError.stack && myError.message) {
  // it's an error, probably
}

However, duck-typing may produce false positives if you have non-error objects that contain stack and message properties.

Try: moment({ // Options here }).format('HHmm'). That should give you the time in a 24 hour format.

Most probably it has to do with caching on the device. Catching the exception and ignoring is not nice but my problem was fixed and it seems to work.

If you want to use numpy, you must define darr to be a numpy array, not a list:

import numpy as np
darr = np.array([1, 3.14159, 1e100, -2.71828])
print(darr.min())

darr.argmin() will give you the index corresponding to the minimum.

The reason you were getting an error is because argmin is a method understood by numpy arrays, but not by Python lists.

I find this works better:

SELECT type, *

Filtering VIEW_DEFINTION inside INFORMATION_SCHEMA.VIEWS is giving me quite a few false positives.

What solved it for me was using :

regasm.exe 'xx.dll' /tlb /codebase /register

It is however, important to understand the difference between regasm.exe and regsvr.exe:

What is difference between RegAsm.exe and regsvr32? How to generate a tlb file using regsvr32?

Note that you can use other tricks like :

-- One or more wildcard:
       .../Downloads20*/*.csv
--  braces and brackets   
       .../Downloads201[1-5]/book.csv
       .../Downloads201{11,15,19,99}/book.csv

This type of solution did the trick for me:

Parent original = db.Parent.SingleOrDefault<Parent>(t => t.ID == updated.ID);
db.Childs.RemoveRange(original.Childs);
updated.Childs.ToList().ForEach(c => original.Childs.Add(c));
db.Entry<Parent>(original).CurrentValues.SetValues(updated);

Its important to say that this deletes all the records and insert them again. But for my case (less then 10) it´s ok.

I hope it helps.

2021 - keep it simple, use CSS Grid

Lots of these answers are outdated, it's 2020 and we shouldn't be enabling people who are still using IE9. It's way more simple to just use CSS grid.

The code is very simple, and you can easily adjust how many columns there are using the grid-template-columns. See this and then play around with this fiddle to fit your needs.

.grid-list {
  display: grid;
  grid-template-columns: repeat(4, 1fr);
}

<ul class="grid-list">
  <li>item</li>
  <li>item</li>
  <li>item</li>
  <li>item</li>
  <li>item</li>
  <li>item</li>
  <li>item</li>
  <li>item</li>
  <li>item</li>
  <li>item</li>
  <li>item</li>
  <li>item</li>
</ul>

If you want to do this without an extra plugin (like printThis), I think this should work. The idea is to have a special div that will be printed, while everything else is hidden using CSS. This is easier to do if the div is a direct child of the body tag, so you will have to move whatever you want to print to a div like that. S So begin with creating a div with id print-me as a direct child to your body tag. Then use this code to print the div:

$("#btn").click(function () {
    //Copy the element you want to print to the print-me div.
    $("#printarea").clone().appendTo("#print-me");
    //Apply some styles to hide everything else while printing.
    $("body").addClass("printing");
    //Print the window.
    window.print();
    //Restore the styles.
    $("body").removeClass("printing");
    //Clear up the div.
    $("#print-me").empty();
});

The styles you need are these:

@media print {
    /* Hide everything in the body when printing... */
    body.printing * { display: none; }
    /* ...except our special div. */
    body.printing #print-me { display: block; }
}

@media screen {
    /* Hide the special layer from the screen. */
    #print-me { display: none; }
}

The reason why we should only apply the @print styles when the printing class is present is that the page should be printed as normally if the user prints the page by selecting File -> Print.

With this command you will see all changes in the repository path/to/repo that were committed in revision <revision>:

svn diff -c <revision> path/to/repo

The -c indicates that you would like to look at a changeset, but there are many other ways you can look at diffs and changesets. For example, if you would like to know which files were changed (but not how), you can issue

svn log -v -r <revision>

Or, if you would like to show at the changes between two revisions (and not just for one commit):

svn diff -r <revA>:<revB> path/to/repo

Set display: table for parent div and display: table-cell for children divs

HTML :

<div class="container-fluid">
  <div class="row justify-content-center display-as-table">

    <div class="col-4 hidden-md-down" id="yellow">
      XXXX<br />
      XXXX<br />
      XXXX<br />
      XXXX<br />
      XXXX<br />
      XXXX<br />vv
      XXXX<br />
    </div>

    <div class="col-10 col-sm-10 col-md-10 col-lg-8 col-xl-8" id="red">
      Form Goes Here
    </div>
  </div>
</div>

CSS:

#yellow {
  height: 100%;
  background: yellow;
  width: 50%;
}
#red {background: red}

.container-fluid {bacgkround: #ccc}

/* this is the part make equal height */
.display-as-table {display: table; width: 100%;}
.display-as-table > div {display: table-cell; float: none;}

Actually, it works, but you also need to do $_SESSION = array(); after the session_destroy to get rid of $_SESSION variables. However, avoid doing unset($_SESSION) because that makes sessions useless.

You should be aware of the current conflicts that exists with iOS and RGBA backgrounds.

Summary: public React Native currently exposes the iOS layer shadow properties more-or-less directly, however there are a number of problems with this:

1) Performance when using these properties is poor by default. That's because iOS calculates the shadow by getting the exact pixel mask of the view, including any tranlucent content, and all of its subviews, which is very CPU and GPU-intensive. 2) The iOS shadow properties do not match the syntax or semantics of the CSS box-shadow standard, and are unlikely to be possible to implement on Android. 3) We don't expose the layer.shadowPath property, which is crucial to getting good performance out of layer shadows.

This diff solves problem number 1) by implementing a default shadowPath that matches the view border for views with an opaque background. This improves the performance of shadows by optimizing for the common usage case. I've also reinstated background color propagation for views which have shadow props - this should help ensure that this best-case scenario occurs more often.

For views with an explicit transparent background, the shadow will continue to work as it did before ( shadowPath will be left unset, and the shadow will be derived exactly from the pixels of the view and its subviews). This is the worst-case path for performance, however, so you should avoid it unless absolutely necessary. Support for this may be disabled by default in future, or dropped altogether.

For translucent images, it is suggested that you bake the shadow into the image itself, or use another mechanism to pre-generate the shadow. For text shadows, you should use the textShadow properties, which work cross-platform and have much better performance.

Problem number 2) will be solved in a future diff, possibly by renaming the iOS shadowXXX properties to boxShadowXXX, and changing the syntax and semantics to match the CSS standards.

Problem number 3) is now mostly moot, since we generate the shadowPath automatically. In future, we may provide an iOS-specific prop to set the path explicitly if there's a demand for more precise control of the shadow.

    apt-get install -y python3.6

Some times you have contributed more by removing code than adding

I think you are trying to capitalize first and last character of each word in a sentence with space as delimiter.

Can be done through StringBuffer:

public static String toFirstLastCharUpperAll(String string){
    StringBuffer sb=new StringBuffer(string);
        for(int i=0;i<sb.length();i++)
            if(i==0 || sb.charAt(i-1)==' ' //for first character of string/each word
                || i==sb.length()-1 || sb.charAt(i+1)==' ') //for last character of string/each word
                sb.setCharAt(i, Character.toUpperCase(sb.charAt(i)));
     return sb.toString();
}

For Xcode6+/iOS8+

~/Library/Developer/CoreSimulator/Devices/[DeviceID]/data/Containers/Data/Application/[AppID]/

Accepted answer is correct for SDK 3.2 - SDK 4 replaces the /User folder in that path with a number for each of the legacy iPhone OS/iOS versions it can simulate, so the path becomes:

~/Library/Application Support/iPhone Simulator/[OS version]/Applications/[appGUID]/

if you have the previous SDK installed alongside, its 3.1.x simulator will continue saving its data in:

~/Library/Application Support/iPhone Simulator/User/Applications/[appGUID]/

When you want to use a parameter from the actual strings.xml file without using any Java code:

<resources>
    <string name="app_name">&appname;</string>

This does not work across resource files, i.e. variables must be copied into each XML file that needs them.

You can't style buttons as links reliably throughout browsers. I've tried it, but there's always some weird padding, margin or font issues in some browser. Either live with letting the button look like a button, or use onClick and preventDefault on a link.

it will have some effect on an object.... query for the result of the effect. If it has no visible effect its not worth unit testing!

DataSet ds = new DataSet();

DataTable activity = DTsetgvActivity.Copy();
activity.TableName = "activity";
ds.Tables.Add(activity);

DataTable Honer = DTsetgvHoner.Copy();
Honer.TableName = "Honer";
ds.Tables.Add(Honer);

I think I see your problem, you need to use the @ syntax to define parameters you will pass in this way, also I'm not sure what loginID or password are doing you don't seem to define them anywhere and they are not being used as URL parameters so are they being sent as query parameters?

This is what I can suggest based on what I see so far:

.factory('MagComments', function ($resource) {
    return $resource('http://localhost/dooleystand/ci/api/magCommenct/:id', {
      loginID : organEntity,
      password : organCommpassword,
      id : '@magId'
    });
  })

The @magId string will tell the resource to replace :id with the property magId on the object you pass it as parameters.

I'd suggest reading over the documentation here (I know it's a bit opaque) very carefully and looking at the examples towards the end, this should help a lot.

SELECT (sub)queries return result sets. So you need to use IN, not = in your WHERE clause.

Additionally, as shown in this answer you cannot modify the same table from a subquery within the same query. However, you can either SELECT then DELETE in separate queries, or nest another subquery and alias the inner subquery result (looks rather hacky, though):

DELETE FROM posts WHERE id IN (
    SELECT * FROM (
        SELECT id FROM posts GROUP BY id HAVING ( COUNT(id) > 1 )
    ) AS p
)

Or use joins as suggested by Mchl.

This is not exactly a hot topic, but I have a factory class that allows a dll to create an instance and return it as a DLL. It is what I came looking for but couldn't find exactly.

It is called like,

IHTTP_Server *server = SN::SN_Factory<IHTTP_Server>::CreateObject();
IHTTP_Server *server2 =
      SN::SN_Factory<IHTTP_Server>::CreateObject(IHTTP_Server_special_entry);

where IHTTP_Server is the pure virtual interface for a class created either in another DLL, or the same one.

DEFINE_INTERFACE is used to give a class id an interface. Place inside interface;

An interface class looks like,

class IMyInterface
{
    DEFINE_INTERFACE(IMyInterface);

public:
    virtual ~IMyInterface() {};

    virtual void MyMethod1() = 0;
    ...
};

The header file is like this

#if !defined(SN_FACTORY_H_INCLUDED)
#define SN_FACTORY_H_INCLUDED

#pragma once

The libraries are listed in this macro definition. One line per library/executable. It would be cool if we could call into another executable.

#define SN_APPLY_LIBRARIES(L, A)                          \
    L(A, sn, "sn.dll")                                    \
    L(A, http_server_lib, "http_server_lib.dll")          \
    L(A, http_server, "")

Then for each dll/exe you define a macro and list its implementations. Def means that it is the default implementation for the interface. If it is not the default, you give a name for the interface used to identify it. Ie, special, and the name will be IHTTP_Server_special_entry.

#define SN_APPLY_ENTRYPOINTS_sn(M)                                     \
    M(IHTTP_Handler, SNI::SNI_HTTP_Handler, sn, def)                   \
    M(IHTTP_Handler, SNI::SNI_HTTP_Handler, sn, special)

#define SN_APPLY_ENTRYPOINTS_http_server_lib(M)                        \
    M(IHTTP_Server, HTTP::server::server, http_server_lib, def)

#define SN_APPLY_ENTRYPOINTS_http_server(M)

With the libraries all setup, the header file uses the macro definitions to define the needful.

#define APPLY_ENTRY(A, N, L) \
    SN_APPLY_ENTRYPOINTS_##N(A)

#define DEFINE_INTERFACE(I) \
    public: \
        static const long Id = SN::I##_def_entry; \
    private:

namespace SN
{
    #define DEFINE_LIBRARY_ENUM(A, N, L) \
        N##_library,

This creates an enum for the libraries.

    enum LibraryValues
    {
        SN_APPLY_LIBRARIES(DEFINE_LIBRARY_ENUM, "")
        LastLibrary
    };

    #define DEFINE_ENTRY_ENUM(I, C, L, D) \
        I##_##D##_entry,

This creates an enum for interface implementations.

    enum EntryValues
    {
        SN_APPLY_LIBRARIES(APPLY_ENTRY, DEFINE_ENTRY_ENUM)
        LastEntry
    };

    long CallEntryPoint(long id, long interfaceId);

This defines the factory class. Not much to it here.

    template <class I>
    class SN_Factory
    {
    public:
        SN_Factory()
        {
        }

        static I *CreateObject(long id = I::Id )
        {
            return (I *)CallEntryPoint(id, I::Id);
        }
    };
}

#endif //SN_FACTORY_H_INCLUDED

Then the CPP is,

#include "sn_factory.h"

#include <windows.h>

Create the external entry point. You can check that it exists using depends.exe.

extern "C"
{
    __declspec(dllexport) long entrypoint(long id)
    {
        #define CREATE_OBJECT(I, C, L, D) \
            case SN::I##_##D##_entry: return (int) new C();

        switch (id)
        {
            SN_APPLY_CURRENT_LIBRARY(APPLY_ENTRY, CREATE_OBJECT)
        case -1:
        default:
            return 0;
        }
    }
}

The macros set up all the data needed.

        // assert(defaultEntryArray[id] == interfaceId, "Request to create an object for the wrong interface.")
        enum SN::LibraryValues l = libraryForEntryPointArray[id];

        f_entrypoint f = libraryFunctionArray[l];
        if (!f)
        {
            HINSTANCE hGetProcIDDLL = LoadLibraryA(libraryPathArray[l]);

            if (!hGetProcIDDLL) {
                return NULL;
            }

            // resolve function address here
            f = (f_entrypoint)GetProcAddress(hGetProcIDDLL, "entrypoint");
            if (!f) {
                return NULL;
            }
            libraryFunctionArray[l] = f;
        }
        return f(id);
    }
}

Each library includes this "cpp" with a stub cpp for each library/executable. Any specific compiled header stuff.

#include "sn_pch.h"

Setup this library.

#define SN_APPLY_CURRENT_LIBRARY(L, A) \
    L(A, sn, "sn.dll")

An include for the main cpp. I guess this cpp could be a .h. But there are different ways you could do this. This approach worked for me.

#include "../inc/sn_factory.cpp"

 img {
     display: block;
     margin-left: auto;
   }

Try the following, not sure which will work for all browsers or the browser you are working with, but it would be best to try all:

<textarea style="overflow:auto"></textarea>

Or

<textarea style="overflow:hidden"></textarea>

...As suggested above

You can also try adding this, I never used it before, just saw it posted on a site today:

<textarea style="resize:none"></textarea>

This last option would remove the ability to resize the textarea. You can find more information on the CSS resize property here

In my case I had to add the public key to my repo (at Bitbucket) AND use git clone once via ssh to answer yes to the "known host" question the first time.

It's not clear exactly what you want to do with the index of a substring [update: it is clearer now - thanks] but you may be able to use the function substring-after or substring-before:

substring-before('My name is Fred', 'Fred')

returns 'My name is '.

If you need more detailed control, the substring() function can take two or three arguments: string, starting-index, length. Omit length to get the whole rest of the string.

There is no index-of() function for strings in XPath (only for sequences, in XPath 2.0). You can use string-length(substring-before($string, $substring))+1 if you specifically need the position.

There is also contains($string, $substring). These are all documented here. In XPath 2.0 you can use regular expression matching.

(XSLT mostly uses XPath for selecting nodes and processing values, so this is actually more of an XPath question. I tagged it thus.)

Note:

1. Its not necessary to specify table name in Person.hbm.xml (........) when you are creating table with same as class name. Also applicable to fields.

2. While creating "person" table in your respective database,make sure that whatever FILEDS names you specified in Person.hbm.xml must match with table COLUMNS names ELSE you wil get above error.

this code will return duplicate value in same array

$array = array(12,43,66,21,56,43,43,78,78,100,43,43,43,21);
foreach($arr as $key=>$item){
  if(array_count_values($arr)[$item] > 1){
     echo "Found Matched value : ".$item." <br />";
  }
}

To add all the changes you've made:

git add .

To commit them:

git commit -m "MY MESSAGE HERE" #-m is the message flag

You can put those steps together like this:

git commit -a -m "MY MESSAGE HERE"

To push your committed changes from your local repository to your remote repository:

git push origin master

You might have to type in your username/password for github after this. Here's a good primer on using git. A bit old, but it covers what's going on really well.

this is the DOM element on which the event was hooked. this.id is its ID. No need to wrap it in a jQuery instance to get it, the id property reflects the attribute reliably on all browsers.

$("select").change(function() {    
    alert("Changed: " + this.id);
}

Live example

You're not doing this in your code sample, but if you were watching a container with several form elements, that would give you the ID of the container. If you want the ID of the element that triggered the event, you could get that from the event object's target property:

$("#container").change(function(event) {
    alert("Field " + event.target.id + " changed");
});

Live example

(jQuery ensures that the change event bubbles, even on IE where it doesn't natively.)

The real answer is: you can't reverse it in place, but you can create a new string that is the reverse.

Just as an exercise to play with recursion: sometimes when you go to an interview, the interviewer may ask you how to do this using recursion, and I think the "preferred answer" might be "I would rather not do this in recursion as it can easily cause a stack overflow" (because it is O(n) rather than O(log n). If it is O(log n), it is quite difficult to get a stack overflow -- 4 billion items could be handled by a stack level of 32, as 2 ** 32 is 4294967296. But if it is O(n), then it can easily get a stack overflow.

Sometimes the interviewer will still ask you, "just as an exercise, why don't you still write it using recursion?" And here it is:

String.prototype.reverse = function() {
    if (this.length <= 1) return this;
    else return this.slice(1).reverse() + this.slice(0,1);
}

test run:

var s = "";
for(var i = 0; i < 1000; i++) {
    s += ("apple" + i);
}
console.log(s.reverse());

output:

999elppa899elppa...2elppa1elppa0elppa

To try getting a stack overflow, I changed 1000 to 10000 in Google Chrome, and it reported:

RangeError: Maximum call stack size exceeded

I was able to fix my Code 1 by running Visual Studio as Admin. Apparently it didn't have access to execute the shell commands without Admin.

No, no, no! Please do not try to make your own 'abstract' classes and methods when the language does not support that feature; the same goes for any language feature you wish a given language supported. There is no correct way to implement abstract methods in TypeScript. Just structure your code with naming conventions such that certain classes are never directly instantiated, but without explicitly enforcing this prohibition.

Also, the example above is only going to provide this enforcement at run time, NOT at compile time, as you would expect in Java/C#.

It's a very old question but I will answer this for future references.

To add any file to emulator just drag and drop the file.

The file will be copied to downloads folder of internal storage.

To access the file

Go to settings

Click On Storage & USB

Click On Internal Storage

Click On Explore (at the end)

and you got it in the downloads folder

now you will get notification to setup virtual SD card, follow the setup. after the successful setup you will be able to see pictures in gallery.

Based on Alex answer above (https://stackoverflow.com/a/11022431/1466341) I came up with even better solution. Solution which doesn't contain exact one record ID.

Assuming that the comma separated list is in table data.list, and it contains listing of codes from other table classification.code, you can do something like:

SELECT 
    d.id, d.list, c.code
FROM 
    classification c
    JOIN data d
        ON d.list REGEXP CONCAT('[[:<:]]', c.code, '[[:>:]]');

So if you have tables and data like this:

CLASSIFICATION (code varchar(4) unique): ('A'), ('B'), ('C'), ('D')
MY_DATA (id int, list varchar(255)): (100, 'C,A,B'), (150, 'B,A,D'), (200,'B')

above SELECT will return

(100, 'C,A,B', 'A'),
(100, 'C,A,B', 'B'),
(100, 'C,A,B', 'C'),
(150, 'B,A,D', 'A'),
(150, 'B,A,D', 'B'),
(150, 'B,A,D', 'D'),
(200, 'B', 'B'),

If you're using Rails 3.2 or Rails 4 you should use request.original_url to get the current URL.

Documentation for the method is at http://api.rubyonrails.org/classes/ActionDispatch/Request.html#method-i-original_url but if you're curious the implementation is:

def original_url
  base_url + original_fullpath
end

If you define your ListView programatically:

mListView.setDescendantFocusability(ListView.FOCUS_BLOCK_DESCENDANTS);

You have to use the FormulaEvaluator, as shown here. This will return a value that is either the value present in the cell or the result of the formula if the cell contains such a formula :

FileInputStream fis = new FileInputStream("/somepath/test.xls");
Workbook wb = new HSSFWorkbook(fis); //or new XSSFWorkbook("/somepath/test.xls")
Sheet sheet = wb.getSheetAt(0);
FormulaEvaluator evaluator = wb.getCreationHelper().createFormulaEvaluator();

// suppose your formula is in B3
CellReference cellReference = new CellReference("B3"); 
Row row = sheet.getRow(cellReference.getRow());
Cell cell = row.getCell(cellReference.getCol()); 

if (cell!=null) {
    switch (evaluator.evaluateFormulaCell(cell)) {
        case Cell.CELL_TYPE_BOOLEAN:
            System.out.println(cell.getBooleanCellValue());
            break;
        case Cell.CELL_TYPE_NUMERIC:
            System.out.println(cell.getNumericCellValue());
            break;
        case Cell.CELL_TYPE_STRING:
            System.out.println(cell.getStringCellValue());
            break;
        case Cell.CELL_TYPE_BLANK:
            break;
        case Cell.CELL_TYPE_ERROR:
            System.out.println(cell.getErrorCellValue());
            break;

        // CELL_TYPE_FORMULA will never occur
        case Cell.CELL_TYPE_FORMULA: 
            break;
    }
}

if you need the exact contant (ie the formla if the cell contains a formula), then this is shown here.

Edit : Added a few example to help you.

first you get the cell (just an example)

Row row = sheet.getRow(rowIndex+2);    
Cell cell = row.getCell(1);   

If you just want to set the value into the cell using the formula (without knowing the result) :

 String formula ="ABS((1-E"+(rowIndex + 2)+"/D"+(rowIndex + 2)+")*100)";    
 cell.setCellFormula(formula);    
 cell.setCellStyle(this.valueRightAlignStyleLightBlueBackground);

if you want to change the message if there is an error in the cell, you have to change the formula to do so, something like

IF(ISERR(ABS((1-E3/D3)*100));"N/A"; ABS((1-E3/D3)*100))

(this formula check if the evaluation return an error and then display the string "N/A", or the evaluation if this is not an error).

if you want to get the value corresponding to the formula, then you have to use the evaluator.

Hope this help,
Guillaume

I know it's a several years old post and you may solve your problem with above solution. However, i just want to suggest using InverseProperty for someone who still need. At least you don't need to change anything in OnModelCreating.

The below code is un-tested.

public class Team
{
    [Key]
    public int TeamId { get; set;} 
    public string Name { get; set; }

    [InverseProperty("HomeTeam")]
    public virtual ICollection<Match> HomeMatches { get; set; }

    [InverseProperty("GuestTeam")]
    public virtual ICollection<Match> GuestMatches { get; set; }
}


public class Match
{
    [Key]
    public int MatchId { get; set; }

    public float HomePoints { get; set; }
    public float GuestPoints { get; set; }
    public DateTime Date { get; set; }

    public virtual Team HomeTeam { get; set; }
    public virtual Team GuestTeam { get; set; }
}

You can read more about InverseProperty on MSDN: https://msdn.microsoft.com/en-us/data/jj591583?f=255&MSPPError=-2147217396#Relationships

Below is the Update query which includes JOIN & WHERE both. Same way we can use multiple join/where clause, Hope it will help you :-

UPDATE opportunities_cstm oc JOIN opportunities o ON oc.id_c = o.id
 SET oc.forecast_stage_c = 'APX'
 WHERE o.deleted = 0
   AND o.sales_stage IN('ABC','PQR','XYZ')

Thank Alexander, I found a way how to modify format for en lang. (Didn't know which lang uses such format)

 $.webshims.formcfg = {
        en: {
            dFormat: '/',
            dateSigns: '/',
            patterns: {
                d: "yy/mm/dd"
            }
        }
     };

 $.webshims.activeLang('en');

Thanks Rich, I will take note of that. So here is the script for my own solution. It requires no third party unzip tools.

Include the script below at the start of the batch file to create the function, and then to call the function, the command is... cscript /B j_unzip.vbs zip_file_name_goes_here.zip

Here is the script to add to the top...

Everythings works well. You can't use divtag.onclick, becease "onclick" attribute doesn't exist. You need first create this attribute by using .setAttribute(). Look on this http://reference.sitepoint.com/javascript/Element/setAttribute . You should read documentations first before you start giving "-".

if (Test-Path C:\DockerVol\SelfCertSSL) {
    write-host "Folder already exists."
} else {
   New-Item -Path "C:\DockerVol\" -Name "SelfCertSSL" -ItemType "directory"
}

<input type="checkbox" checked="checked" />

or simply

<input type="checkbox" checked />

for checked checkbox. No checked attribute (<input type="checkbox" />) for unchecked checkbox.

reference: http://www.w3.org/TR/html-markup/input.checkbox.html#input.checkbox.attrs.checked

You can code an iterator block that lets you execute a code block in an orchestrated fashion. How the code block is broken up really doesn't have to correspond to anything, it's just how you want to code it. For example:

IEnumerable<int> CountToTen()
{
    System.Console.WriteLine("1");
    yield return 0;
    System.Console.WriteLine("2");
    System.Console.WriteLine("3");
    System.Console.WriteLine("4");
    yield return 0;
    System.Console.WriteLine("5");
    System.Console.WriteLine("6");
    System.Console.WriteLine("7");
    yield return 0;
    System.Console.WriteLine("8");
    yield return 0;
    System.Console.WriteLine("9");
    System.Console.WriteLine("10");
}

In this case, when you call CountToTen, nothing actually executes, yet. What you get is effectively a state machine generator, for which you can create a new instance of the state machine. You do this by calling GetEnumerator(). The resulting IEnumerator is effectively a state machine that you can drive by calling MoveNext(...).

Thus, in this example, the first time you call MoveNext(...) you will see "1" written to the console, and the next time you call MoveNext(...) you will see 2, 3, 4, and then 5, 6, 7 and then 8, and then 9, 10. As you can see, it's a useful mechanism for orchestrating how things should occur.

Please check this example here: Accessing Structure Members

There is explained that the right way to do it is like this:

strcpy(s1.name , "Egzona");
printf( "Name : %s\n", s1.name);

This answers is for command needed for undoing local changes which are in multiple specific files in same or multiple folders (or directories). This answers specifically addresses question where a user has more than one file but the user doesn't want to undo all local changes:

if you have one or more files you could apply the same command (git checkout -- file ) to each of those files by listing each of their location separated by space as in:

git checkout -- name1/name2/fileOne.ext nameA/subFolder/fileTwo.ext

mind the space above between name1/name2/fileOne.ext nameA/subFolder/fileTwo.ext

For multiple files in the same folder:

If you happen to need to discard changes for all of the files in a certain directory, use the git checkout as follows:

git checkout -- name1/name2/*

The asterisk in the above does the trick of undoing all files at that location under name1/name2.

And, similarly the following can undo changes in all files for multiple folders:

git checkout -- name1/name2/* nameA/subFolder/*

again mind the space between name1/name2/* nameA/subFolder/* in the above.

Note: name1, name2, nameA, subFolder - all of these example folder names indicate the folder or package where the file(s) in question may be residing.

Tags are not sent to the remote repository by the git push command. We need to explicitly send these tags to the remote server by using the following command:

git push origin <tagname>

We can push all the tags at once by using the below command:

git push origin --tags

Here are some resources for complete details on git tagging:

extending accepted answer with jquery

what if you want to add more canvas?, this jquery.each answer it

responsiveCanvas(); //first init
$(window).resize(function(){
  responsiveCanvas(); //every resizing
  stage.update(); //update the canvas, stage is object of easeljs

});
function responsiveCanvas(target){
  $(canvas).each(function(e){

    var parentWidth = $(this).parent().outerWidth();
    var parentHeight =  $(this).parent().outerHeight();
    $(this).attr('width', parentWidth);
    $(this).attr('height', parentHeight);
    console.log(parentWidth);
  })

}

it will do all the job for you

why we dont set the width or the height via css or style? because it will stretch your canvas instead of make it into expecting size

A fourth option to those you mention are binary files. Although that sounds arcane and difficult, it's really easy with the serialization API in .NET.

Whether you choose binary or XML files, you can use the same serialization API, although you would use different serializers.

To binary serialize a class, it must be marked with the [Serializable] attribute or implement ISerializable.

You can do something similar with XML, although there the interface is called IXmlSerializable, and the attributes are [XmlRoot] and other attributes in the System.Xml.Serialization namespace.

If you want to use a relational database, SQL Server Compact Edition is free and very lightweight and based on a single file.

Fake loop that breaks on the first iteration:

$key = $value = NULL;
foreach ($array as $key => $value) {
    break;
}

echo "$key = $value\n";

Or use each() (warning: deprecated as of PHP 7.2.0):

reset($array);
list($key, $value) = each($array);

echo "$key = $value\n";

If anyone comes here after me, this is the answer that worked for me.

NOTE: please make to read the comments before using this, this not complete. The best advice for update queries I can give is to switch to SqlServer ;)

update mytable t
set z = (
  with comp as (
    select b.*, 42 as computed 
    from mytable t 
    where bs_id = 1
  )
  select c.computed
  from  comp c
  where c.id = t.id
)

Good luck,

GJ

If you're getting this error from Netbeans (7.2+) then it means that your separately installed version of Subversion is higher than the version in netbeans. In my case Netbeans (v7.3.1) had SVN v1.7 and I'd just upgraded my SVN to v1.8.

If you look in Tools > Options > Miscellaneous (tab) > Versioning (tab) > Subversion (pane), set the Preferred Client = CLI, then you can set the path the the installed SVN which for me was C:\Program Files\TortoiseSVN\bin.

More can be found on the Netbeans Subversion Clients FAQ.

Would this parser help you?

https://github.com/fiann/jquery.ogp

It parses meta OG data to JSON, so you can just use the data directly. If you prefer, you can read/write them directly using JQuery, of course. For example:

$("meta[property='og:title']").attr("content", document.title);
$("meta[property='og:url']").attr("content", location.toString());

Note the single-quotes around the attribute values; this prevents parse errors in jQuery.

Here is a little code from my side :)

needed driver:

com.mysql.jdbc.Driver

download: here (Platform Independent)

connection string in one line:

jdbc:mysql://localhost:3306/db-name?user=user_name&password=db_password&useSSL=false

example code:

public static void testDB(){
    try {
        Class.forName("com.mysql.jdbc.Driver");
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }

    try {
        Connection connection = DriverManager.getConnection(
                "jdbc:mysql://localhost:3306/db-name?user=user_name&password=db_password&useSSL=false");
        if (connection != null) {
            Statement statement = connection.createStatement();
            if (statement != null) {
                ResultSet resultSet = statement.executeQuery("select * from test");
                if (resultSet != null) {
                    ResultSetMetaData meta = resultSet.getMetaData();
                    int length = meta.getColumnCount();
                    while(resultSet.next())
                    {
                        for(int i = 1; i <= length; i++){
                            System.out.println(meta.getColumnName(i) + ": " + resultSet.getString(meta.getColumnName(i)));
                        }
                    }
                    resultSet.close();
                }
                statement.close();
            }
            connection.close();
        }
    } catch (Throwable throwable) {
        throwable.printStackTrace();
    }
}

If you need only the application name, not the package name, then just write this code.

 String app_name = packageInfo.applicationInfo.loadLabel(getPackageManager()).toString();

string path=@"E:\AppServ\Example.txt";

if(!File.Exists(path))
{
   File.Create(path).Dispose();

   using( TextWriter tw = new StreamWriter(path))
   {
      tw.WriteLine("The very first line!");
   }

}    
else if (File.Exists(path))
{
   using(TextWriter tw = new StreamWriter(path))
   {
      tw.WriteLine("The next line!");
   }
}

If you have an Order class, adding a property that references another class in your model, for instance Customer should be enough to let EF know there's a relationship in there:

public class Order
{
    public int ID { get; set; }

    // Some other properties

    // Foreign key to customer
    public virtual Customer Customer { get; set; }
}

You can always set the FK relation explicitly:

public class Order
{
    public int ID { get; set; }

    // Some other properties

    // Foreign key to customer
    [ForeignKey("Customer")]
    public string CustomerID { get; set; }
    public virtual Customer Customer { get; set; }
}

The ForeignKeyAttribute constructor takes a string as a parameter: if you place it on a foreign key property it represents the name of the associated navigation property. If you place it on the navigation property it represents the name of the associated foreign key.

What this means is, if you where to place the ForeignKeyAttribute on the Customer property, the attribute would take CustomerID in the constructor:

public string CustomerID { get; set; }
[ForeignKey("CustomerID")]
public virtual Customer Customer { get; set; }

EDIT based on Latest Code You get that error because of this line:

[ForeignKey("Parent")]
public Patient Patient { get; set; }

EF will look for a property called Parent to use it as the Foreign Key enforcer. You can do 2 things:

1) Remove the ForeignKeyAttribute and replace it with the RequiredAttribute to mark the relation as required:

[Required]
public virtual Patient Patient { get; set; }

Decorating a property with the RequiredAttribute also has a nice side effect: The relation in the database is created with ON DELETE CASCADE.

I would also recommend making the property virtual to enable Lazy Loading.

2) Create a property called Parent that will serve as a Foreign Key. In that case it probably makes more sense to call it for instance ParentID (you'll need to change the name in the ForeignKeyAttribute as well):

public int ParentID { get; set; }

In my experience in this case though it works better to have it the other way around:

[ForeignKey("Patient")]
public int ParentID { get; set; }

public virtual Patient Patient { get; set; }

For SQL Server, from http://msdn.microsoft.com/en-us/library/ms179859.aspx :

• % Any string of zero or more characters.

  WHERE title LIKE '%computer%' finds all book titles with the word 'computer' anywhere in the book title.

• _ Any single character.

  WHERE au_fname LIKE '_ean' finds all four-letter first names that end with ean (Dean, Sean, and so on).

• [ ] Any single character within the specified range ([a-f]) or set ([abcdef]).

  WHERE au_lname LIKE '[C-P]arsen' finds author last names ending with arsen and starting with any single character between C and P, for example Carsen, Larsen, Karsen, and so on. In range searches, the characters included in the range may vary depending on the sorting rules of the collation.

• [^] Any single character not within the specified range ([^a-f]) or set ([^abcdef]).

  WHERE au_lname LIKE 'de[^l]%' all author last names starting with de and where the following letter is not l.

I think using dtype where there is a name row is confusing the routine. Try

>>> r = np.genfromtxt(fname, delimiter=',', names=True)
>>> r

You have two options, either float:left or display:inline-block.

Both methods have their caveats. It seems that display:inline-block is more common nowadays, as it avoids some of the issues of floating.

Read this article http://designshack.net/articles/css/whats-the-deal-with-display-inline-block/ or this one http://www.vanseodesign.com/css/inline-blocks/ for a more in detail discussion.

For a good quality x264 encoding of 1060i, done by a computer, not a mobile device, not in real time, you could use a bitrate at about 5 MBps. That means 2250 MB/hour of encoded material. Recommend you deinterlace the footage and compress as progressive.

Listing all the databases in mongoDB console is using the command show dbs.

For more information on this, refer the Mongo Shell Command Helpers that can be used in the mongo shell.

Use .AddRange to append any Enumrable collection to the list.

Eg:

Datatable newTable =  new DataTable();

            foreach(string s1 in list)
            {
                if (s1 != string.Empty) {
                    dvProducts.RowFilter = "(CODE like '" + serachText + "*') AND (CODE <> '" + s1 + "')";
                    foreach(DataRow dr in dvProducts.ToTable().Rows)
                    {
                       newTable.ImportRow(dr);
                    }
                }
            }
ListView1.DataSource = newTable;
ListView1.DataBind();

I had the same question but applying the provided solutions changed the file to write in. Once I selected the new excel file, I was also writing in that file and not in my original file. My solution for this issue is below:

Sub GetData()

    Dim excelapp As Application
    Dim source As Workbook
    Dim srcSH1 As Worksheet
    Dim sh As Worksheet
    Dim path As String
    Dim nmr As Long
    Dim i As Long

    nmr = 20

    Set excelapp = New Application

    With Application.FileDialog(msoFileDialogOpen)
        .AllowMultiSelect = False
        .Filters.Add "Excel Files", "*.xlsx; *.xlsm; *.xls; *.xlsb", 1
        .Show
        path = .SelectedItems.Item(1)
    End With

    Set source = excelapp.Workbooks.Open(path)
    Set srcSH1 = source.Worksheets("Sheet1")
    Set sh = Sheets("Sheet1")

    For i = 1 To nmr
        sh.Cells(i, "A").Value = srcSH1.Cells(i, "A").Value
    Next i

End Sub

With excelapp a new application will be called. The with block sets the path for the external file. Finally, I set the external Workbook with source and srcSH1 as a Worksheet within the external sheet.

you can try this, but you must be sure the type of values for each Column

List<MyClass> result = myDataTable.AsEnumerable().Select(x=> new MyClass(){
     Property1 = (string)x.Field<string>("ColumnName1"),
     Property2 = (int)x.Field<int>("ColumnName2"),
     Property3 = (bool)x.Field<bool>("ColumnName3"),    
});

All I had to do was set the Minimum SDK Version to 21 in File > Project Structure > App > Flavors

Make sure to learn from the padding oracle asp.net vulnerability that just happened (you applied the patch, right? ...) and use protected sections to encrypt the machine key and any other sensitive configuration.

An alternative option is to set it in the machine level web.config, so its not even in the web site folder.

To generate it do it just like the linked article in David's answer.

select dateadd(dd,360,getdate()) will give you correct date as shown below:

2017-09-30 15:40:37.260

I just ran the query and checked:

string a = @"a\\b";
a = a.Replace(@"\\",@"\");

should work. Remember that in the watch Visual STudio show the "\" escaped so you see "\" in place of a single one.

The & makes the command run in the background.

From man bash:

If a command is terminated by the control operator &, the shell executes the command in the background in a subshell. The shell does not wait for the command to finish, and the return status is 0.

If you are in a directory where only root have access to write in system. Then you can directly use wget www.example.com/wget-test using a standard user account. So it will hit the url but because of having no write permission file won't be saved.. This method is working fine for me as i am using this method for a cronjob. Thanks.

sthx

1. The syntax for specifying url is {% url namespace:url_name %}. So, check if you have added the app_name in urls.py.
2. In my case, I had misspelled the url_name. The urls.py had the following content path('<int:question_id>/', views.detail, name='question_detail') whereas the index.html file had the following entry <li><a href="{% url 'polls:detail' question.id %}">{{ question.question_text }}</a></li>. Notice the incorrect name.

Just use the function plot as follows

figure()
...
plot(t, a)
plot(t, b)
plot(t, c)

This is my sample code for load static variable

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class OnelinkConfig {
    public static int MODULE_CODE;
    public static int DEFAULT_PAGE;
    public static int DEFAULT_SIZE;

    @Autowired
    public void loadOnelinkConfig(@Value("${onelink.config.exception.module.code}") int code,
            @Value("${onelink.config.default.page}") int page, @Value("${onelink.config.default.size}") int size) {
        MODULE_CODE = code;
        DEFAULT_PAGE = page;
        DEFAULT_SIZE = size;
    }
}

1)your id should have sys dba access 2)

select sum(a.value) total_cur, avg(a.value) avg_cur, max(a.value) max_cur, 
 s.username, s.machine
 from v$sesstat a, v$statname b, v$session s 
 where a.statistic# = b.statistic# and s.sid=a.sid
 and b.name = 'opened cursors current' 
 group by s.username, s.machine
 order by 1 desc;

To decode:

byte[] image = Base64.getDecoder().decode(base64string);

To encode:

String text = Base64.getEncoder().encodeToString(imageData);

You can try this:

<input type="hidden" name="image" id="input-image{{ image_row }}" />

inputt= '<input type="hidden" name="product_image' value="somevalue">

$("#input-image"+row).remove().append(inputt);

You can use Git GUI on Windows, see instructions:

1. Open the Git Gui (After installing the Git on your computer).

2. Clone your repository to your local hard drive:

3. After cloning, GUI opens, choose: "Rescan" for changes that you made:

4. You will notice the scanned files:

5. Click on "Stage Changed":

6. Approve and click "Commit":

7. Click on "Push":

8. Click on "Push":

9. Wait for the files to upload to git:

You can combine attribute selectors this way:

$("[attr1=val][attr2=val]")...

so that an element has to satisfy both conditions. Of course you can use this for more than two. Also, don't do [type=checkbox]. jQuery has a selector for that, namely :checkbox so the end result is:

$("input:checkbox[name=ProductCode]")...

Attribute selectors are slow however so the recommended approach is to use ID and class selectors where possible. You could change your markup to:

<input type="checkbox" class="ProductCode" name="ProductCode"value="396P4"> 
<input type="checkbox" class="ProductCode" name="ProductCode"value="401P4"> 
<input type="checkbox" class="ProductCode" name="ProductCode"value="F460129">

allowing you to use the much faster selector of:

$("input.ProductCode")...

You can check it with for example jQuery:

$("#elementID").css('display');

It will return string with information about display property of this element.

IIS 6.0 and previous versions :

ASP.NET integrated with IIS via an ISAPI extension, a C API ( C Programming language based API ) and exposed its own application and request processing model.

This effectively exposed two separate server( request / response ) pipelines, one for native ISAPI filters and extension components, and another for managed application components. ASP.NET components would execute entirely inside the ASP.NET ISAPI extension bubble AND ONLY for requests mapped to ASP.NET in the IIS script map configuration.

Requests to non ASP.NET content types:- images, text files, HTML pages, and script-less ASP pages, were processed by IIS or other ISAPI extensions and were NOT visible to ASP.NET.

The major limitation of this model was that services provided by ASP.NET modules and custom ASP.NET application code were NOT available to non ASP.NET requests

What's a SCRIPT MAP ?

Script maps are used to associate file extensions with the ISAPI handler that executes when that file type is requested. The script map also has an optional setting that verifies that the physical file associated with the request exists before allowing the request to be processed

A good example can be seen here

IIS 7 and above

IIS 7.0 and above have been re-engineered from the ground up to provide a brand new C++ API based ISAPI.

IIS 7.0 and above integrates the ASP.NET runtime with the core functionality of the Web Server, providing a unified(single) request processing pipeline that is exposed to both native and managed components known as modules ( IHttpModules )

What this means is that IIS 7 processes requests that arrive for any content type, with both NON ASP.NET Modules / native IIS modules and ASP.NET modules providing request processing in all stages This is the reason why NON ASP.NET content types (.html, static files ) can be handled by .NET modules.

• You can build new managed modules (IHttpModule) that have the ability to execute for all application content, and provided an enhanced set of request processing services to your application.
• Add new managed Handlers ( IHttpHandler)

I got around this by temporarily rewriting my function to something like this:

IF OBJECT_ID ('[dbo].[fx_dosomething]', 'TF') IS NOT NULL
  drop function [dbo].[fx_dosomething];
GO

create FUNCTION dbo.fx_dosomething ( @x numeric )
returns @t table (debug varchar(100), x2 numeric)
as
begin
 declare @debug varchar(100)
 set @debug = 'printme';

 declare @x2 numeric
 set @x2 = 0.123456;

 insert into @t values (@debug, @x2)
 return 
end
go

select * from fx_dosomething(0.1)

I'd say it in another way:

In java references are passed (but not objects) and these references are passed-by-value (the reference itself is copied and you have 2 references as a result and you have no control under the 1st reference in the method).

Just saying: pass-by-value might be not clear enough for beginners. For instance in Python the same situation but there are articles, which describe that they call it pass-by-reference, only cause references are used.

Interestingly, compiling does prove more efficient for me (Python 2.5.2 on Win XP):

import re
import time

rgx = re.compile('(\w+)\s+[0-9_]?\s+\w*')
str = "average    2 never"
a = 0

t = time.time()

for i in xrange(1000000):
    if re.match('(\w+)\s+[0-9_]?\s+\w*', str):
    #~ if rgx.match(str):
        a += 1

print time.time() - t

Running the above code once as is, and once with the two if lines commented the other way around, the compiled regex is twice as fast

The following steps are necessary to create .exe i.e. executable files which are as 1) Open visual studio framework 2) Then, create a new project or application 3) Build or execute your application by pressing F5

Install and use the Android Drawable Importer plugin:

https://github.com/winterDroid/android-drawable-importer-intellij-plugin

Instructions on how to install the plugin are on that page. It's called "Android Drawable Importer" in the plugin search results.

Once installed:

1. right click on "res" folder and select New -> Batch Drawable Import
2. hit the + and select your source image
3. choose what resolution you want it considered and which other sizes to auto-generate for

Seems kind of ridiculous that Android Studio doesn't support this directly.

EDIT: But Xcode doesn't either so.... :-(

When calling a function that is declared with throws in Swift, you must annotate the function call site with try or try!. For example, given a throwing function:

func willOnlyThrowIfTrue(value: Bool) throws {
  if value { throw someError }
}

this function can be called like:

func foo(value: Bool) throws {
  try willOnlyThrowIfTrue(value)
}

Here we annotate the call with try, which calls out to the reader that this function may throw an exception, and any following lines of code might not be executed. We also have to annotate this function with throws, because this function could throw an exception (i.e., when willOnlyThrowIfTrue() throws, then foo will automatically rethrow the exception upwards.

If you want to call a function that is declared as possibly throwing, but which you know will not throw in your case because you're giving it correct input, you can use try!.

func bar() {
  try! willOnlyThrowIfTrue(false)
}

This way, when you guarantee that code won't throw, you don't have to put in extra boilerplate code to disable exception propagation.

try! is enforced at runtime: if you use try! and the function does end up throwing, then your program's execution will be terminated with a runtime error.

Most exception handling code should look like the above: either you simply propagate exceptions upward when they occur, or you set up conditions such that otherwise possible exceptions are ruled out. Any clean up of other resources in your code should occur via object destruction (i.e. deinit()), or sometimes via defered code.

func baz(value: Bool) throws {

  var filePath = NSBundle.mainBundle().pathForResource("theFile", ofType:"txt")
  var data = NSData(contentsOfFile:filePath)

  try willOnlyThrowIfTrue(value)

  // data and filePath automatically cleaned up, even when an exception occurs.
}

If for whatever reason you have clean up code that needs to run but isn't in a deinit() function, you can use defer.

func qux(value: Bool) throws {
  defer {
    print("this code runs when the function exits, even when it exits by an exception")
  }

  try willOnlyThrowIfTrue(value)
}

Most code that deals with exceptions simply has them propagate upward to callers, doing cleanup on the way via deinit() or defer. This is because most code doesn't know what to do with errors; it knows what went wrong, but it doesn't have enough information about what some higher level code is trying to do in order to know what to do about the error. It doesn't know if presenting a dialog to the user is appropriate, or if it should retry, or if something else is appropriate.

Higher level code, however, should know exactly what to do in the event of any error. So exceptions allow specific errors to bubble up from where they initially occur to the where they can be handled.

Handling exceptions is done via catch statements.

func quux(value: Bool) {
  do {
    try willOnlyThrowIfTrue(value)
  } catch {
    // handle error
  }
}

You can have multiple catch statements, each catching a different kind of exception.

  do {
    try someFunctionThatThowsDifferentExceptions()
  } catch MyErrorType.errorA {
    // handle errorA
  } catch MyErrorType.errorB {
    // handle errorB
  } catch {
    // handle other errors
  }

For more details on best practices with exceptions, see http://exceptionsafecode.com/. It's specifically aimed at C++, but after examining the Swift exception model, I believe the basics apply to Swift as well.

For details on the Swift syntax and error handling model, see the book The Swift Programming Language (Swift 2 Prerelease).

It's not possible to specify expiration. It's completely up to the user.

https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage

Of course, it's possible that something your application stores on the client may not be there later. The user can explicitly get rid of local storage, or the browser may run into space considerations. It's good to program defensively. Generally however things remain "forever" based on some practical definition of that word.

edit — obviously, your own application can actively remove stuff if it decides it's too old. That is, you can explicitly include some sort of timestamp in what you've got saved, and then use that later to decide whether or not information should be flushed.

New CKeditor doesn't have file manager included (CKFinder is payable). You can integrate free filemanager that is good looking and easy to implement in CKeditor.

http://labs.corefive.com/2009/10/30/an-open-file-manager-for-ckeditor-3-0/

You dowload it, copy it to your project. All instructions are there but you basically just put path to added filemanager index.html page in your code.

CKEDITOR.replace( 'meeting_notes',
{
startupFocus : true,
toolbar :
[
['ajaxsave'],
['Bold', 'Italic', 'Underline', '-', 'NumberedList', 'BulletedList', '-', 'Link', 'Unlink' ],
['Cut','Copy','Paste','PasteText'],
['Undo','Redo','-','RemoveFormat'],
['TextColor','BGColor'],
['Maximize', 'Image']
],
filebrowserUploadUrl : '/filemanager/index.html' // you must write path to filemanager where you have copied it.
});    

Most languages are supported (php, asp, MVC && aspx - ashx,...)).

In the end I made a jQuery plugin that will format the <input type="number" /> appropriately for me. I also noticed on some mobile devices the min and max attributes don't actually prevent you from entering lower or higher numbers than specified, so the plugin will account for that too. Below is the code and an example:

(function($) {_x000D_
  $.fn.currencyInput = function() {_x000D_
    this.each(function() {_x000D_
      var wrapper = $("<div class='currency-input' />");_x000D_
      $(this).wrap(wrapper);_x000D_
      $(this).before("<span class='currency-symbol'>$</span>");_x000D_
      $(this).change(function() {_x000D_
        var min = parseFloat($(this).attr("min"));_x000D_
        var max = parseFloat($(this).attr("max"));_x000D_
        var value = this.valueAsNumber;_x000D_
        if(value < min)_x000D_
          value = min;_x000D_
        else if(value > max)_x000D_
          value = max;_x000D_
        $(this).val(value.toFixed(2)); _x000D_
      });_x000D_
    });_x000D_
  };_x000D_
})(jQuery);_x000D_
_x000D_
$(document).ready(function() {_x000D_
  $('input.currency').currencyInput();_x000D_
});

.currency {_x000D_
  padding-left:12px;_x000D_
}_x000D_
_x000D_
.currency-symbol {_x000D_
  position:absolute;_x000D_
  padding: 2px 5px;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
<input type="number" class="currency" min="0.01" max="2500.00" value="25.00" />

Added as a comment, but posting as an answer for visibility:

There seems to also be an issue if you initially setup a table view as "static cells" and then change it to "dynamic prototypes." I had an issue where even the delegate method for heightForRowAtIndexPath was being ignored. I first resolved it by directly editing the storyboard XML, then finally just rebuilt the storyboard scene from scratch, using dynamic prototypes from the start.

Try this solution.

$mainModelData = mainModel::where('column', $value)
    ->join('relationModal', 'main_table_name.relation_table_column', '=', 'relation_table.id')
    ->orderBy('relation_table.title', 'ASC')
    ->with(['relationModal' => function ($q) {
        $q->where('column', 'value');
    }])->get();

Example:

$user = User::where('city', 'kullu')
    ->join('salaries', 'users.id', '=', 'salaries.user_id')
    ->orderBy('salaries.amount', 'ASC')
    ->with(['salaries' => function ($q) {
        $q->where('amount', '>', '500000');
    }])->get();

You can change the column name in join() as per your database structure.

In order an element to appear in front of another you have to give higher z-index to the front element, and lower z-index to the back element, also you should indicate position: absolute/fixed...

Example:

<div style="z-index:100; position: fixed;">Hello</div>
<div style="z-index: -1;">World</div>

I would like to suggest yet another alternative that I find the cleanest, but it requires react-redux or something simular - also I'm using a few other fancy features along the way:

// actions.js
export const someAction = (items) => ({
    type: 'SOME_ACTION',
    payload: {items},
});

// Component.jsx
import {connect} from "react-redux";

const Component = ({boundSomeAction}) => (<div
    onClick={boundSomeAction}
/>);

const mapState = ({otherReducer: {items}}) => ({
    items,
});

const mapDispatch = (dispatch) => bindActionCreators({
    someAction,
}, dispatch);

const mergeProps = (mappedState, mappedDispatches) => {
    // you can only use what gets returned here, so you dont have access to `items` and 
    // `someAction` anymore
    return {
        boundSomeAction: () => mappedDispatches.someAction(mappedState.items),
    }
});

export const ConnectedComponent = connect(mapState, mapDispatch, mergeProps)(Component);

// (with  other mapped state or dispatches) Component.jsx
import {connect} from "react-redux";

const Component = ({boundSomeAction, otherAction, otherMappedState}) => (<div
    onClick={boundSomeAction}
    onSomeOtherEvent={otherAction}
>
    {JSON.stringify(otherMappedState)}
</div>);

const mapState = ({otherReducer: {items}, otherMappedState}) => ({
    items,
    otherMappedState,
});

const mapDispatch = (dispatch) => bindActionCreators({
    someAction,
    otherAction,
}, dispatch);

const mergeProps = (mappedState, mappedDispatches) => {
    const {items, ...remainingMappedState} = mappedState;
    const {someAction, ...remainingMappedDispatch} = mappedDispatch;
    // you can only use what gets returned here, so you dont have access to `items` and 
    // `someAction` anymore
    return {
        boundSomeAction: () => someAction(items),
        ...remainingMappedState,
        ...remainingMappedDispatch,
    }
});

export const ConnectedComponent = connect(mapState, mapDispatch, mergeProps)(Component);

If you want to reuse this you'll have to extract the specific mapState, mapDispatch and mergeProps into functions to reuse elsewhere, but this makes dependencies perfectly clear.

I think a lot of times when you see this code, it's from people who are in the habit of event handlers for forms, buttons, inputs, and things of that sort.

Basically, when you have something like:

<form onsubmit="return callSomeFunction();"></form>

or

<a href="#" onclick="return callSomeFunction();"></a>`

and callSomeFunction() returns true, then the form or a will submit, otherwise it won't.

Other more obvious general purposes for returning true or false as a result of a function are because they are expected to return a boolean.

This project has been tested with Xcode 10 and Swift 4.2.

Create a new project

It can be just a Single View App.

Add the code

Create a new Cocoa Touch Class file (File > New > File... > iOS > Cocoa Touch Class). Name it MyCollectionViewCell. This class will hold the outlets for the views that you add to your cell in the storyboard.

import UIKit
class MyCollectionViewCell: UICollectionViewCell {
    
    @IBOutlet weak var myLabel: UILabel!
}

We will connect this outlet later.

Open ViewController.swift and make sure you have the following content:

import UIKit
class ViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate {
    
    let reuseIdentifier = "cell" // also enter this string as the cell identifier in the storyboard
    var items = ["1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28", "29", "30", "31", "32", "33", "34", "35", "36", "37", "38", "39", "40", "41", "42", "43", "44", "45", "46", "47", "48"]
    
    
    // MARK: - UICollectionViewDataSource protocol
    
    // tell the collection view how many cells to make
    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return self.items.count
    }
    
    // make a cell for each cell index path
    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        
        // get a reference to our storyboard cell
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier, for: indexPath as IndexPath) as! MyCollectionViewCell
        
        // Use the outlet in our custom class to get a reference to the UILabel in the cell
        cell.myLabel.text = self.items[indexPath.row] // The row value is the same as the index of the desired text within the array.
        cell.backgroundColor = UIColor.cyan // make cell more visible in our example project
        
        return cell
    }
    
    // MARK: - UICollectionViewDelegate protocol
    
    func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
        // handle tap events
        print("You selected cell #\(indexPath.item)!")
    }
}

Notes

• UICollectionViewDataSource and UICollectionViewDelegate are the protocols that the collection view follows. You could also add the UICollectionViewFlowLayout protocol to change the size of the views programmatically, but it isn't necessary.
• We are just putting simple strings in our grid, but you could certainly do images later.

Set up the storyboard

Drag a Collection View to the View Controller in your storyboard. You can add constraints to make it fill the parent view if you like.

Make sure that your defaults in the Attribute Inspector are also

• Items: 1
• Layout: Flow

The little box in the top left of the Collection View is a Collection View Cell. We will use it as our prototype cell. Drag a Label into the cell and center it. You can resize the cell borders and add constraints to center the Label if you like.

Write "cell" (without quotes) in the Identifier box of the Attributes Inspector for the Collection View Cell. Note that this is the same value as let reuseIdentifier = "cell" in ViewController.swift.

And in the Identity Inspector for the cell, set the class name to MyCollectionViewCell, our custom class that we made.

Hook up the outlets

• Hook the Label in the collection cell to myLabel in the MyCollectionViewCell class. (You can Control-drag.)
• Hook the Collection View delegate and dataSource to the View Controller. (Right click Collection View in the Document Outline. Then click and drag the plus arrow up to the View Controller.)

Finished

Here is what it looks like after adding constraints to center the Label in the cell and pinning the Collection View to the walls of the parent.

Making Improvements

The example above works but it is rather ugly. Here are a few things you can play with:

Background color

In the Interface Builder, go to your Collection View > Attributes Inspector > View > Background.

Cell spacing

Changing the minimum spacing between cells to a smaller value makes it look better. In the Interface Builder, go to your Collection View > Size Inspector > Min Spacing and make the values smaller. "For cells" is the horizontal distance and "For lines" is the vertical distance.

Cell shape

If you want rounded corners, a border, and the like, you can play around with the cell layer. Here is some sample code. You would put it directly after cell.backgroundColor = UIColor.cyan in code above.

cell.layer.borderColor = UIColor.black.cgColor
cell.layer.borderWidth = 1
cell.layer.cornerRadius = 8

See this answer for other things you can do with the layer (shadow, for example).

Changing the color when tapped

It makes for a better user experience when the cells respond visually to taps. One way to achieve this is to change the background color while the cell is being touched. To do that, add the following two methods to your ViewController class:

// change background color when user touches cell
func collectionView(_ collectionView: UICollectionView, didHighlightItemAt indexPath: IndexPath) {
    let cell = collectionView.cellForItem(at: indexPath)
    cell?.backgroundColor = UIColor.red
}

// change background color back when user releases touch
func collectionView(_ collectionView: UICollectionView, didUnhighlightItemAt indexPath: IndexPath) {
    let cell = collectionView.cellForItem(at: indexPath)
    cell?.backgroundColor = UIColor.cyan
}

Here is the updated look:

CSS grids to the rescue

Similar to the flex answers above, this can also be done using CSS Grids. This gives you more scope to offset the title, and a more simple way of expanding the gap between the lines (using grid-template-columns) and the content (using grid-gap).

The benefits of this method over flex methods is the ease of being able to offset the lines, and additionally only needing to add in a gap between columns once (not twice, for each the :before and :after pseudo element). It is also much more syntactically cleaner and obvious IMO.

h1 {
  display: grid;
  grid-template-columns: 1fr auto 1fr;
  align-items: center;
  grid-gap: 1rem;
}

h1:before,
h1:after {
  content: "";
  display: block;
  border-top: 2px solid currentColor;
}

h1.offset {
  grid-template-columns: 1fr auto 3fr;
}

h1.biggap {
  grid-gap: 4rem;
}

<h1>This is a title</h1>

<h1 class="offset">Offset title</h1>

<h1 class="biggap">Gappy title</h1>

<h1>
  <span>Multi-line<br />title</span>
</h1>

You can simply cast strings to DateTime:

[DateTime]"2020-7-16"

or

[DateTime]"Jul-16"

or

$myDate = [DateTime]"Jul-16";

And you can format the resulting DateTime variable by doing something like this:

'{0:yyyy-MM-dd}' -f [DateTime]'Jul-16'

or

([DateTime]"Jul-16").ToString('yyyy-MM-dd')

or

$myDate = [DateTime]"Jul-16";
'{0:yyyy-MM-dd}' -f $myDate

If you have 2 installations of the JVM. Place the version upfront. Linux : export PATH=/usr/lib/jvm/java-8-oracle/bin:$PATH

This eliminates the ambiguity.

The reason your URL is being rewritten to file///K:/AmberCRO%20SOP/2011-07-05/SOP-SOP-3.0.pdf is because you specified http://file://

The http:// at the beginning is the protocol being used, and your browser is stripping out the second colon (:) because it is invalid.

Note

If you link to something like

<a href="file:///K:/yourfile.pdf">yourfile.pdf</a>

The above represents a link to a file called k:/yourfile.pdf on the k: drive on the machine on which you are viewing the URL.

You can do this, for example the below creates a link to C:\temp\test.pdf

<a href="file:///C:/Temp/test.pdf">test.pdf</a>

By specifying file:// you are indicating that this is a local resource. This resource is NOT on the internet.

Most people do not have a K:/ drive.

But, if this is what you are trying to achieve, that's fine, but this is not how a "typical" link on a web page works, and you shouldn't being doing this unless everyone who is going to access your link has access to the (same?) K:/drive (this might be the case with a shared network drive).

You could try

<a href="file:///K:/AmberCRO-SOP/2011-07-05/SOP-SOP-3.0.pdf">test.pdf</a>
<a href="AmberCRO-SOP/2011-07-05/SOP-SOP-3.0.pdf">test.pdf</a>
<a href="2011-07-05/SOP-SOP-3.0.pdf">test.pdf</a>

Note that http://file:///K:/AmberCRO%20SOP/2011-07-05/SOP-SOP-3.0.pdf is a malformed

here i store the PID in a file called .pid (which is kind of like /run/...) and only execute the script if not already being executed.

#!/bin/bash
if [ -f .pid ]; then
  read pid < .pid
  echo $pid
  ps -p $pid > /dev/null
  r=$?
  if [ $r -eq 0 ]; then
    echo "$pid is currently running, not executing $0 twice, exiting now..."
    exit 1
  fi
fi

echo $$ > .pid

# do things here

rm .pid

note: there is a race condition as it does not check how that pid is called. if the system is rebooted and .pid exists but is used by a different application this might lead 'unforeseen consequences'.

To delete records from a table that have a datetime value in Date_column older than 30 days use this query:

USE Database_name;
DELETE FROM Table_name
WHERE Date_column < GETDATE() - 30

...or this:

USE Database_name;
DELETE FROM Table_name
WHERE Date_column < DATEADD(dd,-30,GETDATE())

To delete records from a table that have a datetime value in Date_column older than 12 hours:

USE Database_name;
DELETE FROM Table_name
WHERE Date_column < DATEADD(hh,-12,GETDATE())

To delete records from a table that have a datetime value in Date_column older than 15 minutes:

USE Database_name;
DELETE FROM Table_name
WHERE Date_column < DATEADD(mi,-15,GETDATE())

Downside of all answers here is that they use static field names, so I wrote an adjusted version in OOP style. Assumed you are using getter methods you could directly use this Class and use the field name as parameter. Probably someone find it useful.

class CustomSort{

    public $field = '';

    public function cmp($a, $b)
    {
        /**
         * field for order is in a class variable $field
         * using getter function with naming convention getVariable() we set first letter to uppercase
         * we use variable variable names - $a->{'varName'} would directly access a field
         */
        return strcmp($a->{'get'.ucfirst($this->field)}(), $b->{'get'.ucfirst($this->field)}());
    }

    public function sortObjectArrayByField($array, $field)
    {
        $this->field = $field;
        usort($array, array("Your\Namespace\CustomSort", "cmp"));;
        return $array;
    }
} 

You're right that the SD Card directory is /sdcard but you shouldn't be hard coding it. Instead, make a call to Environment.getExternalStorageDirectory() to get the directory:

File sdDir = Environment.getExternalStorageDirectory();

If you haven't done so already, you will need to give your app the correct permission to write to the SD Card by adding the line below to your Manifest:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

When we have multiple projects in workspace, we have to set the references between the projects, not among the projects. If P1 references P2, P2 references P3, and P3 reference back to P1. That will cause a cycle.

The Solution is to draw a Diagram of the reference between projects in workspace. Check the Java Build Path of each of the projects to see the Tab of the Projects window. Take out the Project that are refering back to the main project, e.g. P3 references P1, in this example above.

Detailed operation is to select P3 project in RAD OR eclipse, right click on the project and choose the properties option, it brings up a new window for properties of P3. Click on the "Java Build Path" section, Choose the "Projects" option Tab. You can see the P3 has referenced P1 in the field. Select the P1 reference, click "Remove" button on the right side of the window. Then, click okay. The IDE will start to reset the path automatically.

Done.

Keep find all of the mis-referenced reference in every each projects until you have the right references to each of the projects in your Diagram. Good Luck!

I don't think the standard HTML select will display HTML content. I'd suggest checking out Bootstrap select: http://silviomoreto.github.io/bootstrap-select/

It has several options for displaying icons or other HTML markup in the select.

<select id="mySelect" data-show-icon="true">
  <option data-content="<i class='glyphicon glyphicon-cutlery'></i>">-</option>
  <option data-subtext="<i class='glyphicon glyphicon-eye-open'></i>"></option>
  <option data-subtext="<i class='glyphicon glyphicon-heart-empty'></i>"></option>
  <option data-subtext="<i class='glyphicon glyphicon-leaf'></i>"></option>
  <option data-subtext="<i class='glyphicon glyphicon-music'></i>"></option>
  <option data-subtext="<i class='glyphicon glyphicon-send'></i>"></option>
  <option data-subtext="<i class='glyphicon glyphicon-star'></i>"></option>
</select>

Here is a demo: https://www.codeply.com/go/l6ClKGBmLS

This should work, I think...

ResultSet results = st.executeQuery(sql);

if(results.next()) { //there is a row
 int id = results.getInt(1); //ID if its 1st column
 String str1 = results.getString(2);
 ...
}

#!/usr/bin/env python
#-*- coding: utf-8 -*-
u = u'moçambique'
print u.encode("utf-8")
print u

chmod +x test.py
./test.py
moçambique
moçambique

./test.py > output.txt
Traceback (most recent call last):
  File "./test.py", line 5, in <module>
    print u
UnicodeEncodeError: 'ascii' codec can't encode character 
u'\xe7' in position 2: ordinal not in range(128)

on shell works , sending to sdtout not , so that is one workaround, to write to stdout .

I made other approach, which is not run if sys.stdout.encoding is not define, or in others words , need export PYTHONIOENCODING=UTF-8 first to write to stdout.

import sys
if (sys.stdout.encoding is None):            
    print >> sys.stderr, "please set python env PYTHONIOENCODING=UTF-8, example: export PYTHONIOENCODING=UTF-8, when write to stdout." 
    exit(1)

so, using same example:

export PYTHONIOENCODING=UTF-8
./test.py > output.txt

will work

new String(byteArray, Charset.defaultCharset())

This will convert a byte array to the default charset in java. It may throw exceptions depending on what you supply with the byteArray.

Try this

> dt.columns.Add("ColumnName", typeof(Give the type you want));
> dt.Rows[give the row no like  or  or any no]["Column name in which you want to add data"] = Value;

If you are using Python2.5 or older try

for newer Python, there is factorial in the math module as given in other answers here

Now that I understand better what you need, here's what I propose. Add a keyup handler for your textbox that checks the textbox contents with this regex ^[0-9]{1,14}\.[0-9]{2}$ and if it doesn't match, make the background red or show a text or whatever you like. Here's the code to put in document.ready

$(document).ready(function() {
    $('selectorForTextbox').bind('keyup', function(e) {
        if (e.srcElement.value.match(/^[0-9]{1,14}\.[0-9]{2}$/) === null) {
            $(this).addClass('invalid');
        } else {
            $(this).removeClass('invalid');
        }
    });
});

Here's a JSFiddle of this in action. Also, do the same regex server side and if it doesn't match, the requirements have not been met. You can also do this check the onsubmit event and not let the user submit the page if the regex didn't match.

The reason for not enforcing the mask upon text inserting is that it complicates things a lot, e.g. as I mentioned in the comment, the user cannot begin entering the valid input since the beggining of it is not valid. It is possible though, but I suggest this instead.

The main difference is that with a = a + b, there is no typecasting going on, and so the compiler gets angry at you for not typecasting. But with a += b, what it's really doing is typecasting b to a type compatible with a. So if you do

int a=5;
long b=10;
a+=b;
System.out.println(a);

What you're really doing is:

int a=5;
long b=10;
a=a+(int)b;
System.out.println(a);

Another solution, You can just iterate over the object keys like so, Note: you must use an instantiated object with existing properties:

printTypeNames<T>(obj: T) {
    const objectKeys = Object.keys(obj) as Array<keyof T>;
    for (let key of objectKeys)
    {
       console.log('key:' + key);
    }
}

I have faced same problem. I solved this by Right click on project --->Team----> Refresh/cleanup

My solution is put those imports in __init__.py of lib:

in file: __init__.py
import mod1

Then,

import lib
lib.mod1

would work fine.

For anyone struggling with this issue, I just found out that the Geocoding API can't be used with API keys that have referrer restrictions. Just remove all your referrer restrictions and you should be good.

If you're using any other APIs that do allow keys with referrer restrictions (like the Maps JS API), it's probably best to create a 2nd key with no restrictions to use exclusively for geocoding, because other APIs might display your key publicly and someone else could start using it on their own site.

Lots of answers found here for creating multidimensional arrays in bash.

And without exception, all are obtuse and difficult to use.

If MD arrays are a required criteria, it is time to make a decision:

Use a language that supports MD arrays

My preference is Perl. Most would probably choose Python. Either works.

Store the data elsewhere

JSON and jq have already been suggested. XML has also been suggested, though for your use JSON and jq would likely be simpler.

It would seem though that Bash may not be the best choice for what you need to do.

Sometimes the correct question is not "How do I do X in tool Y?", but rather "Which tool would be best to do X?"

I normally configure the applicationContext using Annotation based configuration rather than XML based configuration. Anyway, I believe both of them have the same priority.

*Answering your question, system variable has higher priority *

Getting profile based beans from applicationContext

• Use @Profile on a Bean

@Component
@Profile("dev")
public class DatasourceConfigForDev

Now, the profile is dev

Note : if the Profile is given as @Profile("!dev") then the profile will exclude dev and be for all others.

• Use profiles attribute in XML

<beans profile="dev">
    <bean id="DatasourceConfigForDev" class="org.skoolguy.profiles.DatasourceConfigForDev"/>
</beans>

Set the value for profile:

• Programmatically via WebApplicationInitializer interface

  In web applications, WebApplicationInitializer can be used to configure the ServletContext programmatically

@Configuration
public class MyWebApplicationInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
            servletContext.setInitParameter("spring.profiles.active", "dev");
    }
}

• Programmatically via ConfigurableEnvironment

  You can also set profiles directly on the environment:

    @Autowired
    private ConfigurableEnvironment env;

    // ...

    env.setActiveProfiles("dev");

• Context Parameter in web.xml

  profiles can be activated in the web.xml of the web application as well, using a context parameter:

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/app-config.xml</param-value>
    </context-param>
    <context-param>
        <param-name>spring.profiles.active</param-name>
        <param-value>dev</param-value>
    </context-param>

• JVM System Parameter

  The profile names passed as the parameter will be activated during application start-up:

  -Dspring.profiles.active=dev
  

  In IDEs, you can set the environment variables and values to use when an application runs. The following is the Run Configuration in Eclipse:

• Environment Variable

  to set via command line : export spring_profiles_active=dev

Any bean that does not specify a profile belongs to “default” profile.

The priority order is :

1. Context parameter in web.xml
2. WebApplicationInitializer
3. JVM System parameter
4. Environment variable

You can add an event listener with 'ended' as the first param

Like this :

https://stackoverflow.com/a/2880950/6839331

My two cents here:

When you create and add a key to gpg-agent you define something called passphrase. Now that passphrase at some point expires, and gpg needs you to enter it again to unlock your key so that you can start signing again.

When you use any other program that interfaces with gpg, gpg's prompt to you to enter your passphrase does not appear (basically gpg-agent when daemonized cannot possibly show you the input dialog in stdin).

One of the solutions is gpg --sign a_file.txt then enter the passphrase that you have entered when you created your key and then everything should be fine (gpg-agent should automatically sign)

See this answer on how to set longer timeouts for your passphrase so that you do not have to do this all the time.

Or you can completely remove the passphrase with ssh-keygen -p

Edit: Do a man gpg-agent to read some stuff on how to have the above happen automatically and add the lines:

GPG_TTY=$(tty)
export GPG_TTY

on your .bashrc if you are using bash(this is the correct answer but I am keeping my train of thought above as well) then source your .bashrc file or relogin.

As can be seen in this link on their site (http://james.newtonking.com/archive/2009/10/23/efficient-json-with-json-net-reducing-serialized-json-size.aspx) I support using [Default()] to specify default values

Taken from the link

   public class Invoice
{
  public string Company { get; set; }
  public decimal Amount { get; set; }

  // false is default value of bool
  public bool Paid { get; set; }
  // null is default value of nullable
  public DateTime? PaidDate { get; set; }

  // customize default values
  [DefaultValue(30)]
  public int FollowUpDays { get; set; }
  [DefaultValue("")]
  public string FollowUpEmailAddress { get; set; }
}


Invoice invoice = new Invoice
{
  Company = "Acme Ltd.",
  Amount = 50.0m,
  Paid = false,
  FollowUpDays = 30,
  FollowUpEmailAddress = string.Empty,
  PaidDate = null
};

string included = JsonConvert.SerializeObject(invoice,
  Formatting.Indented,
  new JsonSerializerSettings { });

// {
//   "Company": "Acme Ltd.",
//   "Amount": 50.0,
//   "Paid": false,
//   "PaidDate": null,
//   "FollowUpDays": 30,
//   "FollowUpEmailAddress": ""
// }

string ignored = JsonConvert.SerializeObject(invoice,
  Formatting.Indented,
  new JsonSerializerSettings { DefaultValueHandling = DefaultValueHandling.Ignore });

// {
//   "Company": "Acme Ltd.",
//   "Amount": 50.0
// }

Try with this code:

from PIL import Image

Image.fromarray(image).show()

I may guess, the old instance of your program is still running. Windows does not allow to change the files which are currently "in use" and your linker cannot write the new .exe on the top of the running one. Try stopping/killing your program.

I was recently looking for a nice solution to this without adding React-Bootstrap to my project (as Bootstrap 4 is about to be released).

This is my solution: https://jsfiddle.net/16j1se1q/1/

    componentDidMount(){
        $(this.getDOMNode()).modal('show');
        $(this.getDOMNode()).on('hidden.bs.modal', this.props.handleHideModal);
    },
    render(){
        return (
          <div className="modal fade">

                  <h4 className="modal-title">Modal title</h4>
                </div>
                <div className="modal-body">
                  <p>One fine body&hellip;</p>
                </div>
                <div className="modal-footer">
                  <button type="button" className="btn btn-default" data-dismiss="modal">Close</button>
                  <button type="button" className="btn btn-primary">Save changes</button>
                </div>
              </div>
            </div>

        )
    },
    propTypes:{
        handleHideModal: React.PropTypes.func.isRequired
    }
});



let App = React.createClass({
    getInitialState(){
        return {view: {showModal: false}}
    },
    handleHideModal(){
        this.setState({view: {showModal: false}})
    },
    handleShowModal(){
        this.setState({view: {showModal: true}})
    },
    render(){
    return(
        <div className="row">
            <button className="btn btn-default btn-block" onClick={this.handleShowModal}>Open Modal</button>
            {this.state.view.showModal ? <Modal handleHideModal={this.handleHideModal}/> : null}
        </div>
    );
  }
});

React.render(
   <App />,
    document.getElementById('container')
);

The main idea is to only render the Modal component into the React DOM when it is to be shown (in the App components render function). I keep some 'view' state that indicates whether the Modal is currently shown or not.

The 'componentDidMount' and 'componentWillUnmount' callbacks either hide or show the modal (once it is rendered into the React DOM) via Bootstrap javascript functions.

I think this solution nicely follows the React ethos but suggestions are welcome!

If somebody is seeking to update data from one database to another no matter which table they are targeting, there must be some criteria to do it.

This one is better and clean for all levels:

UPDATE dbname1.content targetTable

LEFT JOIN dbname2.someothertable sourceTable ON
    targetTable.compare_field= sourceTable.compare_field
SET
    targetTable.col1  = sourceTable.cola,
    targetTable.col2 = sourceTable.colb, 
    targetTable.col3 = sourceTable.colc, 
    targetTable.col4 = sourceTable.cold 

Traaa! It works great!

With the above understanding, you can modify the set fields and "on" criteria to do your work. You can also perform the checks, then pull the data into the temp table(s) and then run the update using the above syntax replacing your table and column names.

Hope it works, if not let me know. I will write an exact query for you.

I had from a totaly different reason the same notice "Value does not fall within the expected range" from the Visual studio 2008 while trying to use the: Tools -> Windows Embedded Silverlight Tools -> Update Silverlight For Windows Embedded Project.

After spending many ohurs I found out that the problem was that there wasn't a resource file and the update tool looks for the .RC file

Therefor the solution is to add to the resource folder a .RC file and than it works perfectly. I hope it will help someone out there
